What are the Changes in transportation from World War 1 to World War 2?

Not as much as you might think. Most of the German artillery which went into Russia in 1941 was horse drawn. I don't think many horses made it back ! The US in particular produced many lorries in WW2 and of course the tracked vehicle became commonplace. LidDELL-Hart suggests the German Blitkreig, Russia again, would have been much more effective had the support vehicles been tracked to keep pace with the Panzer units. WW2 is much more mobile, but the reason, 1 of them, for the viability of trench warfare in WW1 is the railway system bringing supplies to one same place (Combined with tinned food) The use of air power in WW2 is also massively transforming, there was no use in WW1 of passenger aircraft, they were not in existence. So really its the Lorry, the Tracked Vehicle & the Aeroplane which make the availability of movement so much greater in WW2.
